SEPARABLE BUTToN.

SPECIFICATION kforming part of Letters Patent No. 600,1 14, dated March 1, 1898. Application filed April 22, 1896. Serial No. 588,585. (No model.)

To CLU whom, it may concern:

Be it known that I, EUGENE PRINGLE, a citizen of the United States, and a resident of Gloversville, in the county of Fulton, State of New York, have invented certain new and useful Improvements in Separable Buttons, of which the following is a full, clear, and exact specificatiomsuch as will enable others skilled in the art to which it appert-ains to make and use the same.

The objects of my invention are to produce.

a separable button or fastening device for gloves and other articles lhaving a stud-catch for engagement with the stud member and provided with Van inturned edge or catch-lips on a line with its flange at the lowest point of strain and when slitted to have a protecting washer or guard surrounding the slitted portion to limit the expansion of the catch-lips and to prevent them from being strained; also, to provide means whereby the buttonhead -or socket member of a separable button may be secured to varying thicknesses of material without undue extension of the buttonhead or the stud member above the fabric and forbringing the catching or working parts of both members always in proper relative alinement with each other regardless of the varying thickness of material to which they may be secured; also, to produce a separable button which shall be simple in construction, of comparatively few parts, neat in appearance, and efficient and durable in use. I attain these objects by means of the construction shown in the accompanying drawings, in which* Figure 1 is a vertical central section through the button-head or socket member of a separable button secured to the material. Fig. 2 is a similar view of a modified form of head. Fig. 3 is a sectional View of the button cap or l Fig. 4 is a section of the protecting-washer or stud-catch guard. Fig. 5 is a section of the stud-catch before attachment to the material, said Figs. 3, 4, and 5 showing details of the parts of the buttonhead illustrated in Fig'. l. Figs. 6, 7, and 8 showin detail vertical sections of the parts of the Vbutton-head illustrated in Fig. 2, an unslitted stud-catch being shown therein, Fig. 6 showing the cap, Fig. 7 the contour of the clench-turning piece prior to and after upsetting the fastening-eyelet or clenching portion of the stud-catch, and Fig. 8 the back or closing piece, over which the tubular or clenching end of the stud-catch is turned; and Fig. 9 is a sectional view of the stud-catch and its guard-washer assembled prior to attachinent to the fabric.

For the purpose of better illustration the figures of the drawings exaggerate or show the parts enlarged.

In Figs. l and 3 is shown a head or cap a, having the hollow rim b and the inwardly-turned edges c d, the upper inturned edge c forming a recess or depression, with a seat e for the-clench of Jthe upper end of the stud-catch f, Figs'. 1 and 5. The stud-catch fconsists of a hollow slitted body having the swelled or bulging portion o, which preferably tapers toward the top and is contracted at its lower or stud-engaging end, where an outwardlyturned ange g is formed, and p inwardlyturned lips or acute catching edge h, which serves to engage and hold the stud member 75 detachably but securely within the socket of the socket member or button-head. When the button-head shown in Figs. 1,- 3,4, and 5 is to be secured to the material, (the studcatch fand its guard z' having been previously 8o assembled, as shown in Fig. 9,) the clenching end of the catch is passed up through the material and extends through the cappiece a, anda suitable tool inserted in the top or eyelet portion of the stud-catch turns the edges thereof outward into the recess e, making a clean finish and securely holding the head to the material.

In Figs. 2, 6; 7, and 8 the button-head is' modiiied to permit the use of a closed cap or cover to the head and also'showing means within the button-head for upsetting the clenching end of the stud-catch. a', Figs. 2 and 6, is the cap or cover; b', Figs. 2and 7, the clench-turning piece within the cap, and c', Figs. 2 and 8, the back or closing piece connected to the head in the usual manner, and t', Figs. l, 2, 4, and 9, the stud-catch guard or protecting-washer. When the upper end of the stud-catch, with its guard or washer z' surrounding it below, is passed through the material and into the button-head or cap,the upper or clenching end of the stud-catch strikes the clench-turning piece b' and is spread over the edge of the opening in the closing-piece c', within the recess on the inside of the cap or button-head, and a suitable tool at the same time depresses the convex portion of the clenching-piece to give increased room for the' head of the stud.

My stud-catch may or may not be tapered at the upper end, as shown.

The guard or protecting-washer serves not only to protect the stud-catch from being strained or injured, but serves also as a rigid, unyielding ange for making a secure bearing on and attachment to the material. The lip or flange around the central opening of the guard-washer being raised slightly above the lower surface of the outer body portion forms a receptacle for the iiange of the studcatch on which it rests and gives a smooth and finished appearance to the exposed sur- .face of the button-head when attached to the material.

An important advantage of my form of studcatch is that the catch-lips form an acute catching edge at the lowest possible point and are in line with the catch-groove in the cooperating stud member and are in direct line with the point of greatest strain or pull, and the base-iiange of the stud-catch is in the plane of the catching edge.

Owing to the fact that just above the catchlips h the hollow interior portion of the catch is swelled to substantially t the contour of a stud having a holding-groove, the two members of the button are prevented from having a wabbling action, and this advantage is assisted by the use of a stud having an integra-l base-flange and the rigid guard upon the studcatch.

I have shown in Fig. l a slitted or spring stud-catch for use with a non-resilient stud, while in Fig. 2 is illustrated an unslitted studcatch designed to be used with a slitted or spring stud. In fact any suitable form of stud may be used with my stud-catch, and my studcatch may be used with various kinds of button-heads or may be clenched directly to the material; and I do not desire to be understood as being limited to the details shown.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. A stud-catch consisting.of a barrel-like body portion having at one end an outwardlyextended flange and an inwardly-extending acute catching edge substantially in the same plane with said liange, the body portion of the catch above the catching edge being swelled or bulged, and the unflanged end of the barrel serving as the means whereby the catch is secured to the material, substantially as described.

2. A stud-catch consisting of a hollow body having a clenching portion at one end, an outturned flange at the opposite end, and a contracted portion adjacent to said flange; said contracted portion and flange being slitted to form a resilient holding-catch h for engagement with a stud, and a non-resilient guard seated around said contracted portion in a groove or recess formed above the flange, so as to limit the expansion of the holdin g-catch and to protect the same.

3. The socket member of a separable button consisting of a cap, as a', a back, as c', and a clench-turning piece, as b', interposed between said cap and back; said three pieces being secured together and adapted to rest upon one side of the material to which the button is to be attached, combined with a stud-catch, asf, having a base-flange at one end and a clenching portion at the other, a guard-washer, as t', encircling the base of said catch and having an inner annular lip or liange raised above the lower surface of the surrounding body portion thereof and resting on the iange of the catch; said catch and guard-washer bein g secured together, and the washer being adapted to rest upon the reverse side of the material while the clenching end of the catch is passed through the material and clenched so as to secure said catch and cap together and bind the material between the cap and Washer.

4. Ahollow stud-catch having a base-flange and a resilient holding edge in the plane of said flange and contracted at its lower end so as to form an annular recess above the flange, in combination with a rigid or non-,resilient guard surrounding and inclosing the resilient portion of the catch with its inner edge fitting in said recess; said guard being only sufficiently larger than the catch to permit the engagement and disengagement of the stud, thus preventing undue expansion and injury to the catch, substantially as described.

5. A separable-button catch consisting of a centrally apertured non resilient guardwasher, as t', a slitted hollow stud-catch, as f, enlarged between its ends and having a base-flange, said catch being secured in the aperture of said guard by said flange and enlargement; the upper portion of said catch being constructed to serve as the means whereby the catch and guard-washer are secured to the fabric or button-head, substantially as described.

6. As a new article of manufacture, a studcatch for separable buttons consisting of a hollow body portion having an annular outturned base-flange and contracted at its studengaging end, thereby forming an inturned engaging edge h, on a plane with its outturned flange; the uniianged end of said body portion being constructed to serve as the means for securing said catch to the material or button-head, substantially as described.

7. A stud-catch having a clenching end portion and an outturned ange at its opposite end; said ianged end being contracted and IOO IIO

slitted and having an acute catching edge, in combination with a non-resilient guard surrounding the slitted portion of said catch with its inner edge resting on said flange, substantiallyr as described.

8. A hollow stud-catch for separable buttons having an outturned annular` 'ange at one end and having both of its ends contracted to form openings of substantially the same size, and swelled or bulged between its ends; the langed end of the catch having an inturned catching edge, and. the unlanged end thereof lbeing constructed to serve asv the means for clenching the catch to the material; said outturned flange being in the same plane as the said inturned catching edge, substan- EUGENE PRINGLE.
